1 Ion Exchange Resins PRODUCT DATA SHEET AMBERLITE IRA67 Industrial Grade Weak Base Anion Exchanger AMBERLITE IRA67 resin is a weak base anion The flexible acrylic structure of AMBERLITE IRA67 exchange resin with a gel type acrylic matrix. It has a resin allows for effective adsorption and desorption high capacity, excellent physical stability, fast of naturally occurring organic molecules, such as kinetics, outstanding resistance to organic fouling humic and fulvic acids, that are present in many and basicity higher than that of polystyrenic weak water supplies. base resins.

2 PERFORMANCE Organic matter Operating capacity The aliphatic structure of AMBERLITE IRA67 resin gives it slightly less affinity for organic acids found in The operating exchange capacity of surface waters than polystyrene weak base resins. This AMBERLITE IRA67 resin depends on a weaker affinity combined with the flexible acrylic number of factors: polymer structure allows for more complete elution of composition of water (particularly CO2 and the organics from the resin. Therefore, AMBERLITE SO4 content), IRA67 resin offers a large reversible capacity for the specific flow rate, removal of organic matter. ionic load. HYDRAULIC CHARACTERISTICS AMBERLITE IRA67 resin offers an operating AMBERLITE IRA67 resin gives a pressure drop of capacity 15 to 30 % higher than that of about 18 kPa/m bed depth per 10 m/h at 15 C. A polystyrenic weak base resins. backwash flow rate of 4 m/h gives a bed expansion of The engineering data sheet EDS 0255 A about 65 % at 15 C. provides information to calculate the operating capacity of AMBERLITE IRA67 resin. LIMITS OF USES Regeneration AMBERLITE IRA67 resin is suitable for industrial water treatment. For all other specific applications Optimum regeneration conditions correspond such as pharmaceutical, food processing or potable to a quantity of caustic soda equivalent to 120 water applications, it is recommended that all to 140 % of the operating capacity. It is not potential users seek advice from Rohm and Haas in recommended to use higher regeneration order to determine the best resin choice and ratios, as the excess caustic soda might lead to optimum operating conditions. an increase of the rinse water volume required. The latter can be minimised by recycling the rinse effluent through the upstream cation exchange resin. All our products are produced in ISO 9001 certified manufacturing facilities.

Ion exchange resins and polymeric adsorbents, as produced, contain by-products resulting from the manufacturing process. The user must determine the extent to which organic by-products must be removed for any particular use and establish techniques to assure that the appropriate level of purity is achieved for that use. The user must ensure compliance with all prudent safety standards and regulatory requirements governing the application. Except where specifically otherwise stated, Rohm and Haas Company does not recommend its ion exchange resins or polymeric adsorbents, as supplied, as being suitable or appropriately pure for any particular use. Consult your Rohm and Haas technical representative for further information. Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Nitric acid and other strong oxidising agents can cause explosive type reactions when mixed with Ion Exchange resins. Proper design of process equipment to prevent rapid buildup of pressure is necessary if use of an oxidising agent such as nitric acid is contemplated. Before using strong oxidising agents in contact with Ion Exchange Resins, consult sources knowledgeable in the handling of these materials.
